I've just discovered that the author L.E. Modesitt Jr. has a fascinating blog, which I'm adding to my "In Their Own Words" list as well.
Modesitt is the author of the Recluse books, the latest of which, Arms Commander (amazon.com link), I"m reading right now. He's also written the Spellsong Cycle (fantasy) and numerous science fiction books, including The Parafaith War, Adiamante and The Octagonal Raven. I find the books to be nearly unique in terms of the way they make me think about different issues within the context of the story.
